You are filling in the ANOVA table values for an experiment using a two-factor factorial design.In the experiment, there are two Factor A treatments, four Factor B treatments, and three replications.The interaction sum of squares value turns out to be 6000.The interaction mean square value must be 750.

Question

Quizplus · Accepted Answer

The interaction mean square is calculated by dividing the interaction sum of squares by its degrees of freedom. For a two-factor factorial design with 2 levels of Factor A and 4 levels of Factor B, the degrees of freedom for interaction is (2-1)*(4-1) = 3. Therefore, the interaction mean square would be 6000/3 = 2000, not 750.
